Fibrillated Nanocellulose Obtained by Mechanochemical Processes from Coconut Fiber Residue
S. I. D. S. Silva, C. Pires, et al.
This research, conducted by Sarah Inglid dos Santos Silva, Cassiano Pires, Egon Petersohn Junior, Angela Maria Tribuzy de Magalhães Cordeiro, Rilton Alves de Freitas, and Nataly Albuquerque dos Santos, developed cellulose nanofibrils from green coconut fiber residue using an alkaline pretreatment and colloidal-mill grinding. FTIR, XRD, thermal, AFM and SEM analyses confirmed removal of amorphous components, presence of cellulose I crystallinity, nanometric fiber morphology and a gel-like rheology, yielding pure, renewable cellulose comparable to commercial grades.
